Summary of Fatigue Life Research Method on Rubber Components

This paper summarizes the rubber component's fatigue life research methods, mainly includes the crack nucleation method, the crack propagation method and the S-N curve method, sums up the these methods from different angels of fatigue life, and various methods based on the choices are given; Based on the working conditions and fatigue failure evaluation criteria to choose the appropriate design calculation method, in order to achieve relatively accurate results of fatigue life prediction and simplify the calculation, and separately summarized FEM used in the rubber fatigue life on the application and progress in the recent stage.
